本文介绍在64位Linux系统下使用AT&T语法编写32位汇编程序时遇到的错误：“Error:invalid instructionsuffixfor`push'”，并提供了解决方案：在代码开头添加.code32。

在 Linux 使用 AT&T 语法写汇编程序时

程序中有一条命令为：pushl %eax

使用 as 编译时出现错误：Error: invalid instruction suffix for `push'


原因是 64 位系统和 32 位系统的差别引起的


解决方法为：

在代码开头添加 .code32 即可

end of file not at end of a line; newline inserted 英文的意思就是说文末没有换行符。Unix文档的回车换行符是一个字符\n，Windows的是分别的两个\n\r， 解决方法：在文件结尾回车一下 invalid instruction suffix for `pop' 原因是 64 位系统和 32 位系统的差别引起的 解决方法为： 在代码开头添加 .code32 即可 ...

前面已经成功编译并运行引导程序，现在进行内核部分的编译修改。首先针对Makefile进行修改，现我们定下内核映像文件在build目录下生成，名为system.bin，则对all规则修改：all: build/bootsect.bin build/setup.bin build/system.bin    dd if=build/bootsect.bin of=bootimage-fd.img bs...

【Error】AT&T汇编 报错 Error: invalid instruction suffix for `push' 或 pop

为什么要学AT&T汇编呢？因为喜欢Linux。 关于intel汇编和AT&T汇编的区别，参考LinuxC一站式编程： 要彻底搞清楚C语言的原理，必须要深入到指令一层去理解。你写一行C代码，编译器会生成什 么样的指令，要做到心中有数。 x86 汇编的两种语法：intel 语法和AT&T 语法 x86汇编一直存在两种不同的语法，在intel 的官方文档中使 用intel ...

在64位系统和32位系统的as命令对于某些汇编指令的处理支持不一样造成的。可在代码头部添加.code32，但又会报另外的错：Error: bad register name `%rax', 等一系统不正确的寄存器名。

抱歉，看起来在转换汇编指令时出现了一些问题。尝试使用以下代码，它应该可以在MinGW-w64中正常编译和运行： ```cpp #include #define vPushData 0x10 #define vCall 0x12 #define vEnd 0xff char *str = "Hello...

首先，错误信息提到无效指令后缀和操作数类型不匹配，这可能是因为汇编代码使用了旧的语法，而当前的汇编器（比如GAS）使用的是AT&T语法，而代码可能是为旧的汇编器写的，或者有其他的语法问题。比如，在x86汇编中，...

invalid instruction suffix for `push' 错误原因是，在64位系统和32位系统的as命令对于某些汇编指令的处理支持不一样造成的 在代码头部添加.code32即可。 转载于:https://www.cnblogs.com/xpylovely/p/10554881.html...

(X64下的内联汇编避坑之“mov报错？”) 标题为何32位的代码到64位软脚了？ 首先我们先回顾下关于x64在C标准库中定义的一系列长度变化 以最常用的size_t为例，在64位系统下的size_t也变成了64位： typedef long size_t; 因此，对于有些内嵌汇编教程中的movl指令就必须进行相应的变动；而具体的变动则应当参考man页中的定义进行相关的变动。 举个栗子，有如下代码段 int main(void) { int str_len = 15; const

写在前面（标题一定要长长长） 虽然说是该系列之一，不过也仅此一篇。由于问题有好几个，我就不另开其他的文章记录了，全糅杂于此。实验内容在Linux上编译安装Nachos, 还有搭建交叉编译环境实验环境腾讯云主机 Centos7.0 64位， gcc 4.8.5 Nachos 4.1结果只实现了在centos上编译安装Nachos，没能成功搭建 交叉编译环境 ค(TㅅT)遇到的问题以及解决1
../main.asm(30) : error A2070: invalid instruction operands

<think>嗯，用户遇到了汇编语言中的错误A2070，需要解决。首先，我得回忆一下这个错误的原因。根据之前的引用，这个错误通常是因为操作数无效，尤其是在使用MOVD指令时没有指定操作数的大小。比如，引用2和4提到，需要添加dword ptr来修饰内存操作数，比如将movdmm4, [esp+0]改为movd mm4,dwordptr [esp+0]。这可能是因为汇编器无法推断操作数的大小，所以必须显式指定。用户提到错误出现在main.asm的第30行，所以需要具体检查那一行的代码。可能的错误点包括使用内存操作数而没有指定大小，或者寄存器与操作数类型不匹配。例如，MOVD指令要求目标或源操作数是MMX寄存器或内存地址，并且内存地址必须用dwordptr或qwordptr等修饰符明确大小。另外，引用4指出在Visual Studio2005中，汇编器要求显式指定内存操作数的大小，这可能适用于用户的环境。所以解决方案应该是检查第30行的MOVD或其他类似指令，确保内存操作数前有dword ptr或类似的修饰符。可能还需要考虑其他指令是否有同样的问题，比如MOVQ或其他涉及内存操作的指令。用户应该逐一检查所有出现错误的地方，并添加必要的修饰符。此外，确保寄存器类型与指令匹配，比如MMX指令使用正确的寄存器，避免操作数大小不匹配。 总结步骤：1.定位错误行；2.检查内存操作数是否有大小修饰符；3.添加dword ptr等；4.检查其他类似指令；5.重新编译测试。同时，提供示例代码修改，帮助用户理解如何修正。</think>### 错误 A2070: invalid instruction operands 的解决方案 #### 错误原因分析 错误 `A2070: invalid instruction operands` 表示汇编器无法识别指令的操作数类型或格式，常见于以下场景[^2][^4]： 1. **内存操作数未明确指定大小**：例如 `movd mm4, [esp+0]` 未标注 `dword ptr`，导致汇编器无法推断操作数大小。 2. **寄存器与操作数类型不匹配**：例如将 MMX 寄存器与非对齐内存地址结合使用。 3. **指令语法错误**：操作数顺序或类型违反汇编规则（如 `movd` 要求目标为寄存器，源为内存或立即数）。 #### 解决步骤 1. **定位错误行** 检查 `main.asm` 第 30 行代码，确认具体指令和操作数格式。 2. **添加内存操作数大小修饰符** 若涉及内存操作（如 `[esp+0]`），需用 `dword ptr` 或 `qword ptr` 明确操作数大小： ```asm ; 错误示例 movd mm4, [esp+0] ; 修正示例（添加 dword ptr） movd mm4, dword ptr [esp+0] ``` 3. **检查寄存器兼容性** 确保指令支持的寄存器类型，例如： - `movd` 目标需为 MMX/XMM 寄存器，源需为 32 位寄存器或内存地址。 - 避免混合使用不同位宽的寄存器（如 `eax` 与 `mm0`）。 4. **验证指令语法** 参考汇编器手册确认指令格式，例如： ```asm ; 正确语法示例 movd mm0, dword ptr [eax] ; 从内存加载到 MMX 寄存器 movd dword ptr [ebx], mm1 ; 从 MMX 寄存器保存到内存 ``` 5. **扩展检查** 若其他行存在类似错误（如第 1432、1576 行[^1][^3]），需重复上述步骤修正。 #### 示例修正 假设第 30 行代码为： ```asm movd mm0, [ebp-4] ``` 修正后应为： ```asm movd mm0, dword ptr [ebp-4] ``` #### 验证与测试 重新编译代码，观察错误是否消除。若问题持续，检查其他潜在语法错误（如操作数对齐问题）。 --- ###
